Login failed

[johnwen]

 Hello,

It has suddenly stopped working, I get "login failed" errors and sometimes
"connection to storage server failed ".

I have these files:

config.inc.php  config.inc.php.sample  defaults.inc.php  mimetypes.php

Please tell me how to fix it, it was working fine before

How do I enable Enable imap_debug?

When I uncomment this, roundcube webmail wont open

//Log IMAP conversation to <log_dir>/imap or to syslog
$config['imap_debug'] = true;

imap_debug won't help here. This is IMAP server issue. Check mail log.
